NVIDIA GeForce GTX 590 vs Radeon HD 6990
I like the numbers game – 1024 CUDA cores, 94 ROPs, and 3GB of GDDR5 RAM on board – doesn’t that sound impressive? Thats the new NVIDIA GeForce GTX 590 is. Its indeed a pair of GTX 580 chips glued together. However power constraints have limited that each of these chip is running at a slower pace that what they would run on a single card. The clock’s core speed is stepped down to 607MHz, shaders are only doing 1.2 GHz, and the memory clock is locked at 3.4GHz. But still, there is a huge grunt under that over sized shroud and those who reviewed it have put it to the acid test against AMD’s incumbent single card performance leader, the Radeon HD 6990.
Similar to the GTX 590, the Radeon HD 6990 has got pair of AMD’s finest GPUs and costs a wallet killing $699. Afterl all the tests, lot of benchmarking, testing the awesome graphics prowess, the conclusion was that AMD still outperforms the competetion and retains its title as the winner. But its only marginal. The GTX 590 had a remarkably silent cooler for a heavy duty pixel-pushing performance like that. So mind you AMD fans.
